Any new bullets for a .44 are geared toward hunting (Partition Gold, Barnes, etc.). It would be hard to ever see a difference between them and the XTP you currently use. As for home defense, I have read and kept up with load performance for years and all will tell you that a full house .44 mag is overpenetrative and a waste of energy. That is why your .44 defense loads will be low velocity and a lighter bullet. Just like your elk load, you want your bullet to expend its energy inside the vermin.

I use your same load for hunting but when I carry my 4 5/8" Ruger SB for backup I use the old tried and true .44 Special 200gr. Win. Silvertips. It took me a long time to accept this since I am a magnummaniac but this load is low recoil, practically no muzzle flash, and very accurate in my gun. Indoors this would be great. This is also why some of your manufacturers are rediscovering the .44 Special and chambering carry guns for it.

As for the Glasers, I have never considered them due to the high price and reports of terrible accuracy.
